Siemens SIMOTICS motors are built for demanding industrial drive applications, covering induction motors, synchronous servo motors, and main spindle motors across a wide range of frame sizes, power ratings, and mounting configurations. The collection spans the SIMOTICS M and SIMOTICS S motor families, including 1PH6, 1PH7, and 1PH8 series induction motors for main spindle and vector drive applications, and 1FK7 series synchronous servo motors for motion control and positioning systems. Pre-assembled MOTION-CONNECT power cables for SINAMICS S120 drive systems are also available.
PLC Direct supplies Siemens SIMOTICS motors to customers, maintaining installed drive systems and sourcing replacement mechanical hardware when OEM lead times or lifecycle status make standard distribution unreliable. Our collection covers 886 products across active and legacy motor series.
Where Siemens Motors Are Used
A failed motor in a production line, spindle drive, or process pump circuit disrupts downstream operations until a compatible replacement is sourced and installed. For facilities running SINAMICS S120 drive systems or SINUMERIK CNC installations, the motor is mechanically and electrically matched to the drive. Substituting an incompatible frame size, encoder type, or power rating creates commissioning problems that extend the outage well beyond the initial failure. Sourcing a like-for-like replacement from available independent stock eliminates that delay.
Facilities and applications that depend on Siemens SIMOTICS motors include:
CNC machine tool installations running 1PH7 and 1PH8 main spindle motors paired with SINAMICS S120 drives
Servo positioning and motion control systems using 1FK7 synchronous servo motors
Heavy industrial drives requiring high-torque induction motors in large frame sizes
Process industry installations where SIMOTICS M motors drive pumps, fans, and compressors
Legacy SINAMICS and SIMOVERT drive installations with 1PH6-series motors still in service
Maintenance teams replacing motors in installed systems where the original specification must be matched.
Siemens Motors Products
This collection covers SIMOTICS induction and servo motors, and MOTION-CONNECT power cables for SINAMICS S120 systems. All product families and confirmed part numbers are sourced from the live PLC Direct collection page.
Product Families
1PH8 Series — SIMOTICS M Induction Motors: The 1PH8 series covers compact induction motors for main spindle and vector drive applications, designed for use with SINAMICS S120 drive systems. Available in multiple frame sizes across the 1PH8103, 1PH8107, 1PH8131, 1PH8133, 1PH8165, and 1PH8184 designations, covering a range of power outputs and shaft configurations.

What to Know Before You Buy Siemens Motors
Motor replacement requires more specification matching than most automation components. The replacement must match the original motor's frame size, power rating, shaft configuration, cooling method, encoder type, and connection standard before installation proceeds without modification.
Hardware condition options: We supply Siemens SIMOTICS motors as surplus sealed, refurbished, and used hardware. Surplus sealed units are factory-sealed stock. Refurbished units have been tested and restored to operational condition. For motors going into critical drive applications, confirming the condition grade and verifying mechanical condition before installation is recommended.
Compatibility considerations: 1PH7 and 1PH8 series motors are designed for use with SINAMICS S120 drive systems and must be matched to the drive's motor module type, power rating, and encoder interface. 1FK7 servo motors require drive-side encoder configuration and are not interchangeable with induction motor variants. MOTION-CONNECT power cables are matched to specific motor connection types (SPEED-CONNECT Size 1) and motor module variants; confirm the cable interfaces at both ends before ordering.
Part identification: SIMOTICS motor part numbers encode the series (1PH6, 1PH7, 1PH8, 1FK7), frame size, shaft height, cooling configuration, and encoder type. The suffix characters after the core part number identify mounting and option variants. For legacy 1PH6 and 1PH7 motors, the original nameplate part number is the most reliable reference for sourcing a compatible replacement. Contact us with the full part number, including any -Z suffix configurations.
Warranty: All Siemens SIMOTICS motors purchased from PLC Direct include a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.
